TIRE-TOOL.

Specification of Letters Patent.

Application filed February 4, 1911. Serial No. 606,662.

To all whom it may concern;

Be it known that I, PATRICK E. KENNEY, a citizen of the United States,residing at Celina, in the countyof Mercer and State of Ohio, haveinvented a new and useful Tire-Tool, of which the following is aspecification. 1

Thisfinvent-ion relates to tire tools such as are employed in mountingand dismountdetachable tire two rings are employed, one of which1nterthe rim, and serves to ,r1n firmly in and, with tires as nowgenerally constructed,-

ing automoblle tires.

In holding what isknown as a quick assembled with the rim,

looks with one of the beads of the casing or sheath, and the other ofwhich engages a peripheral channel disposed at one edge of lock thefirst named position against possibilityiof accidental disconnection. Aswill be apparent, this locking ring must be not only resilient, butcomparatively stifi', in order to enable it to withstand the spreadingstrains-to which itwill be subjected in use,

to remove this locking ring, when repairs are necessary to theinner'tube, requlres the out ut of both force and labor, and gen era lythe services of a workman familiar with the operation.

It is the objectof the present invention in a ready and practical mannerto render it easy for any person possessing. the requisite strength todismount a tire, and as readily remount it when repairs are necessary,the operation being accomplished .with the output of but a small amountof labor, in convenience and loss-of time. a

With these and other-objects in view as will appear asthe nature of theinvention is better understood, the same consists, generally stated, n atiretool comprising a, pair of crossed and pivoted levers, one of whichterminates in a relatively'long inward curved I felly engaging hook, andthe other in a relunequal length, the

defining two bills of unequal length, the crotch being designedtoreceive thelocking ring, and the longer bill to forcethe dctachableflange to one side when the locking ring.

isto be positioned In addition, one of the levers terminates in longerof which is debetween the end of the signed to be inserted I contiguouswall of the locking ring, and the channel, and the shorter to beinserted between the locking ringand-detach'able flange,

and are both chisel the walls ofthe longer tine being oblique to anglesto the atively short jaw having. a terminal crotch to receive thelocking ring I a fork having tines of and longer bill 8 will forcewhereby upon downward plied to the tool, the end of the lockingringengaged by the fork will be forced out of the channel.

The invention consists further in the variousnovel details ofconstruction of a the tool, as will be hereinafter fully described andclaimed.

In the accompanying drawings forming a part of this specification, andin which like characters of reference indicate corresponding partsFigure 1 is a view in perspective of a tire tool constructed inaccordance with the present invention. Fig. 2 is a transverse sectionalview through a portion of an automobile tire, showing the first stepobserved in the removal of the tire. Fig. 3 is a erspective detail viewshowing the manner in which the fork of one of the levers operates toremove the locking ring from the rim.

Fig. 4 is a view similar to Fig. 2 showing,

the procedure observed in replacing th'e locking ring to position. Fig;5 isa view similar to Fig. 4, showing aslightly modified form of channeland locking ring. Fig. 6 is a view similar to Fig. 5 showing the mannerin which the-tool is manipulated for detaching the sheath from a rim ordetachable flange should it adhere thereto from rust the-pivot of thelevers, and the bevels of the walls of the shorter tine being at rightpivot, and the crotch of the fork being disposed transversely of the inner walls of the lever 2, for a'purpose that will presently appear.

nates at one end in a jaw 6 having a termi- 'nal crotch v7 that defi'nestwo bills 8 and 9 of unequal length, the crotch being designed when itis to be positioned within the channel, and the inner the detachableflange C out of engagement with the locking ring, when the latter is to'be positioned, as

shown in Fig. 4.

pressure being ap- The lever 2 termi to permit the insertion of the forkat nates the-sheath of an automobile tire, having the usual beads B.

The rim of the automobile wheel is desig nated by the letter R, the samebeing provided at one edge with an outstanding circumferential flange Ffor engaging the bead on one side of the sheath, and at the other edgethe rim is provided with an instanding trough-shaped seat T. The rim Ris mounted upon the usual felly X. The bead B on the side of the rimadjacent the seat T is adapted to be engaged by the detachable flangeGwhich is held in place by the looking ring L, the locking ring beingadapted to engage in the seat T and having the usual inwardly extendingprojection P that is designed to engage the orifice C in the seat. Thisconstruction is common in automobile wheels, and need not be describedin further detail.

, With the parts thus constructed, the mode of dismounting the sheath isas follows. The tire having been entirely deflated, the tool is appliedas shown in Fig. 2, and by swinging the levers upon the tooth of thetelly engaging hook and upon their own pivots will cause the hill 8 toforce or displace the-adjacent detachable flange inward and thus providea space between the detachable iiange and the locking ring L to per mitthe insertion of a cold chisel K of. the

ordinary type, and this will hold the detach ring spaced apart the endof the lever 1 which will assume the position shown in Fig. 3, after thelever is swung that is to say with the longer or inner tine insertedunder the locking ring, and the shorter or outer tine between thelocking and the detachable flange, and upon downward and outwardpressure being applied to the tool, the locking ring will be forced fromits seat. The cold chisel is now removed and is inserted under the endsof the locking ring, and the other tine is forced in between the rim andthe locking ring, and the latter is pried farther out, and thisoperation is repeated at intervals around the rim until a sufiicientlength of the ring has been detached to render it possible to completethe operation by hand. After the necessary repairs to the inner tubehave been made, and the'sheath and detachable flange assembled with therim, the tool is manipulated as shown in Fig. 4:, which will operate toforce the adjacent detachable flange inward to carry the locking ringinward and permit the projection P of the locking ring to enter theorifice O of the able flange and locking Copies of this patent may beobtained for fi've cents seat, and by repeating this operation offorcing the locking ring against the detachable flange, and with the aidof a hammer,

the locking ring may easily and readily be seated.

On some quick detachable tires, the locking ring L Fig. 5 is providedwith a flange Z, and to dismount this character of locking ring, theflange and the short tine above it so that the flange is in the fork,and by bearing down upon the tool, the end of the locking ring will belifted out of the channel, and as the tines pass one above and the otherbelow the flange the ring will be prevented from slipping back. It is tobe understood that the crotch 7 must be large and deep en ough to engagethe entire locking ring in remounting otherwise the latter would falldown and out. i

It will be seen from the foregoing de scription, that although theimprovements herein defined are simple in character, that they will bethoroughly efficient for the purpose designed, and will result in theproduction of a tool that will fill. a long felt want, and one that maybe operated by a person of ordinary mechanical ability.

I claim: I

1. A tire tool comprising a pair of crossed and pivoted levers, one ofwhich has the end thereof hooked inwardly to define a 'felly engagingtooth, and the other lever terminating in a short jaw having a crotch atthe end thereof defining an outer and an inner bill, whereby when thesaid tooth is engaged with the folly of an automobile wheel the leversmay be swung rela tive to the wheel and each other to bring the outerbill against the clenching ring to displace same inwardly, the shorterbill serving to carry the locking ring in position as the clenching ringis forced inwardly.

2. A tire tool comprising a pair of crossed and pivoted levers, one ofwhich. terminates in a felly engaging hook, and the other leverterminating in a short jaw having an outer and an inner bill which areadapted to engage the detachable flange and locking ring of anautomobile wheel, whereby the each, by addressing the Commissioner ofYatents,
